BS about being too small to xray , all the vet needs to do is place hatchling in xray transparent tub with a lid.
I suggest getting hold of some VETAFARM CALCIVET to help boost his calcium intake.
Direct dose: 0.2mL per 100g body weight given orally by syringe , tastes nice , lizards I've helped / rescued liked it's taste and came to regard it as a daily treat (I would be giving it to them 2 or 3 times per day , so 0.2ml/100g body weight / dose frequency per day).
The good kit is a shown here - recommend 22Gauge SureFlo Catheter (TUBE ONLY) to give CalciVet , I've been using these for nearly 10 years.
This is what they look like disassembled
The
flexible white Teflon tube is the bit that's useful in administering liquids and oral meds to lizards, the metal needle assembly is disposed off (carefully !! VERY DANGEROUS AND SHARP).
Best to stay with 22G for fluids, is more durable than the larger bore version where the lizard has teeth.
Be careful the dragon doesn't chew pieces of plastic of the end of the plastic tube.
I found the 14G tube very soft and too easily crushed and holed.
I've had success using this
to get nasty tasting antbiotics and nice tasting CalciVet into skinks , the trick is to get the plastic tube past the lips and teeth at the back corner of the mouth , not necessary force the mouth open but is a two person job
one person restrains the lizard
the other person slips the catheter tube into mouth and pushes the syringe plunger.
I've also used this kind of setup
to get HerpaBoost , VetaFarm Reptile Critta Care and viscous liquid meds into the mouths of lizards, got to get the mouth enough to get the nozzle into the mouth , again a two person job unless the lizard is prepared to lick the paste off it's nose and lips , works well
and for really difficult situations this works and is indestructible and wont hurt the lizard's teeth, gums , jaws or mouth
